Purple bells is a fast-growing, colourful, evergreen shrub that can tolerate some sun during the day, but prefers semi-shaded conditions. It is a plant from a summer-rainfall climate that does well in a wide range of soils, and will thrive in the winter-rainfall areas as long as the soil drains well. Water well in summer, but much less in winter. It has lush foliage when it receives regular reasonable amounts of water, although it is quite hardy and can do alright with less. The plants are frost sensitive.

Feed generously. Lots of compost added to the soil before planting, will keep the plants lush and green. Plants require thick layers of compost applied as mulch and regular feeding with organic or chemical slow release fertilizer to perform at their best.

Regular tip pruning is needed for neat compact growth and to encourage more flowers. A once yearly, slightly heavier pruning will keep this plant sending out fresh growth.

This is an excellent decorative garden plant suitable for use in townhouse gardens, small gardens, Mediterranean- and cottage bed designs, showcasing mixed herbaceous borders. They do well, and look lovely planted near to water features or ponds. Also good for screening and informal hedging, as it responds well to pruning and shaping.

Purple bells is easily propagated from seeds, cuttings and layering.

The seeds must be collected before the capsules burst open, dispersing the seeds. This can be done just as soon as they start to turn brown. Sow in seed trays in a well-drained medium. Cover the seeds with sifted soil or sand. Keep trays in a warm sheltered area until germination occurs. Prick out the seedlings and pot them up when the first true leaves are well established. Grow on untill ready to transplant into the garden.

Layering is also an easy method of propagating this plant, because it roots along the ground as it grows and spreads. Bend a few branches, remove the leaves from a section of each branch then bury that under a layer soil; peg it down if necessary. Keep the soil moist until rooting. When the roots are well grown, lift the rooted runners and plant into individual containers. Water with care untill the plantlings recover, grow on to plant out.

Softwood cuttings can be taken from new growth in summer. Place in a suitable rooting medium, use appropriate rooting hormone powder to increase success. Keep in a warm sheltered area until rooting occurs, which can be expected in 4 to 6 weeks, after which they can be potted up and grown on.
